Thanks for reply. As you can see, english is not my first language, so sorry for any mistakes.
1. If you look astro dealers on google you will find some big broadband company in Malaysia, named Astro, and they are using dealers....and a few car dealers named astrocar, astroford, astrolincoln ans something like this.So I think that some car dealers could use this name.But maybe I am wrong.
2. I was thinking tradingyear could do for some online financial news website or so some traders.
3.I have checked and there are a few website called something metaforical like tasteoflife and others. So I thinking is something you can build on .
4. I think it could work for a glue brand. I have found that there is a company from China who sells a brand of glue named glue-b 6000, 7000, 8000
If you look for glue b on google there are 74 mil results so somebody could use this.
I have now something like 70 domains, but mainly with .eu extension, with page rank and others stuff, using them for websites or reselling, but if I find something I think is good, I am buying on .com or .net extension as well.
